I ordered the mhx 514 for my 21 trd pro and had the dealer install it, they said I was missing a piece that keeps the hoses from rubbing one another, and ordered me the part.

Here it is, I don't know how this mounts in there to keep them from rubbing

 

I think I see where it would go but wouldn't they both still be right next to each other?

 

Hmm that is interesting. Not sure why they said they would need that as the hoses don’t rub on each other or the frame if you cut the hose to the correct length.

 

I'll snap a pic tomorrow of the hoses, seems they were left a little long.

Nothing crazy though. I think they were trying to make it as close to the way the stock 18s were.

 

It will be an easy fix to cut them to the proper length. Please let me know if you have any questions.

 

Will do. Thank you, I'll take a few pics and you can tell me if I should cut them or leave them be or use that little routing/hose holder thingy.

 

Went to homedepot and got 6 rubber clamps and separated the hoses , they were not rubbing but did it just in case and it cost me like 5$

 

Excellent idea! Thank you.

 

I'm trying to figure out what area this is??

 

This is at the back of the wind deflector where the rubber hoses connect to the hard lines at the bottom

 

Got it. Thank you!

 

Just so everyone is aware and not going out buying hose separators. If you remove the excess slack from the hose properly there is no reason to worry about the hose rubbing on anything to include the other hose to cause premature wear.

There will be a install video coming soon which will detail this process and the rest of the install.

 

My lower hose slightly touches the fender metal and brake fluid hose. Should I be concerned? Really don’t want to take it back apart just to cut about 1/2 inch off.

 

It shouldn’t be an issue however, if you do decide to cut some slack on the hose I’d recommend pinning the thermostat open to allow the cooler to drain back to the pan. This will allow you to remove the fittings, slip off the hose, trim and reinstall without losing ATF.

 

Thank you. I was wondering if a bunch of fluid would come out of the line. I think I’ll just monitor the hoses for wear at this point and make adjustments if necessary.

 

Thoughts on applying a braided wire sleeve for protection?

I thought about something like that also. I’d rather not take the clamp and hose off to put the sleeve on. The hose will be stretched out where it was on the nipple and I feel it wouldn’t have as tight of a fit/seal as it initially did. I wonder if there is something that would slip around the line without having to take anything apart.

I think I’ll try some of this where it is touching something. It can be wrapped around without removing the hose.

 

Another happy customer with a 2019-2021 Tundra MHX-514 (Discontinued)

 

Installed my Hayden cooler Saturday on my 21 CM , took off my 19 before sell ,
32 oz fluid put in, went through procedure running it until hitting 103deg on scangauge
Checked fluid level got 33 oz back out , cooler pinned , double checked today same ,
Anyone here that’s installed there’s ran into this on there 21 overfilled ,

 

Was the truck level when conducting the procedure? If so, it’s not unheard of Toyota overfilling transmissions.

 

Leveled yes , yea if I Hadn’t been installing cooler wonder if I would have
Experienced any transmission issues at some point in time,

 

Summer of 2020 bought Nicks kit for my 4 month old truck, checked the fluid level before starting the install. I was surprised when I pulled the level check plug a full stream came out, not even close to a trickel.

 

Haven’t noticed any difference, I always warm up the truck though before I drive , only thing I can think off is your oil level but you already Double checked it

 

I believe Toyota has a different shift logic based upon the transmission temperature. That is why I recommend removing the pin from the thermostat so the transmission get to operating temperature as quick as possible as designed.

 

Besides the ATF level, the colder weather is the only other factor I can think of.

 

Here is a preview of the installation instructions for the Genuine Cooling Systems transmission cooler for 2019-2021 Toyota Tundra with the Setrab Series-9 15-row cooler. When Nick posts the official version I'll edit this post and point to his version. I had already bought this kit a while back but hadn't got to installing it, and it was a pleasure to work with Nick both as a customer buying the kit, and working with him to make this install video. Thank you Nick.

 

Thanks Steve!

 

Is there a reason this was discontinued? Any issues? I just bought this kit and haven't installed yet, if there is a design flaw or something I don't want to install it.
